HEPATITIS B SURFACE ANTIBODY (QNT) TITER
1 mL serum or plasma, collect SST, red top or lavender EDTA. If tube other than a SST is used, transfer separated serum or plasma to a plastic transport tube and indicate specimen type on the tube.
Immunochemiluminometric assay (ICMA)
Room temp: 14 days, Refrigerated: 14 days, Frozen: 14 days
This test is useful for quantitative (i.e. titer) evaluation of possible immunity in individuals who are at increased risk for exposure to hepatitis B (i.e. hemodialysis unit personnel, venipuncturists, etc.). This test can be used to evaluate the need for hepatitis B immune globulin after needlestick injury, to evaluate the need for hepatitis B vaccine and to follow immune status after hepatitis B vaccination.
